Never miss a local story.

When you look at the production of the Saints’ three primary backs, it’s easy to see why.

Peterson signed with the Saints during the offseason but has been lightly used through four games. Used to being a workhorse with the Minnesota Vikings, Peterson has been lightly used in the Big Easy. Heading into Sunday’s game against the Detroit Lions, Peterson had only rushed for 81 yards on 27 carries. Meanwhile Mark Ingram has collected 170 yards on 42 with 15 receptions for another 125 yards. Rookie Alvin Kamara has proven to be a versatile asset for the Saints offense, too, rushing 15 times for 83 yards and a touchdown — the Saints only rushing score. He has also caught 20 passes for 147 yards — both second on the team — with a score.

In parts of 11 seasons, Peterson has averaged 93.1 yards per game. In 127 career games, Peterson has rushed for 11,828 yards and 97 touchdowns.
